Clean dealing is the direct antonym for the word "dirty dealing." It refers to a fair and ethical way of conducting business or other transactions without any hidden agenda or ulterior motives. Clean dealing involves transparency and honesty, which enhances trust between the parties involved in a transaction. It emphasizes the principles of integrity, accountability, and responsibility. Clean dealing also ensures that both parties benefit from the transaction without one party taking advantage of the other. It promotes long-term relationships between the parties involved rather than short-term gains. In summary, clean dealing is the complete opposite of dirty dealing, and it characterizes a respectable and ethical way of conducting business.
